Return value from function in key of array? How do this?

[Bartosz Koselnik]

I don't know how to describe my problem, so I will present an example below.

playground jsr

Maybe you can use the handlebars built in lookup helper
https://handlebarsjs.com/guide/builtin-helpers.html#lookup

And handlebars subexpressions
https://handlebarsjs.com/guide/expressions.html#subexpressions

Maybe something like this.

{{#with (lookup _jsr.fund (test value)) as |fnd|}}
